Methods: Milk samples from 60 mothers were pooled. From this pool, 36 samples were taken; 12 samples were kept raw, 12 samples were HP, and 12 samples were retort processed to create an SS product. Samples were analyzed for percent fat, percent solids, total protein, lactose, amino acids, and thiamine. Results: Percent fat, percent solids, and lactose were similar between raw, HP, and SS samples. Total protein was statistically increased in SS samples when compared to raw (P = 0.005) and HP (P < 0.001) samples, but protein differences were not clinically relevant (raw = 15.1 mg/mL, HP = 14.8 mg/mL, and SS = 15.8 mg/mL). Lysine was the only amino acid impacted by processing, and its destruction increased as heat increased (raw = 0.85 mg/100 mL, HP = 0.77 mg/100 mL, SS = 0.68 mg/100 mL). Total thiamine was significantly decreased in SS samples (0.14 mg/L; P < 0.01) when compared with raw samples (0.24 mg/L) and HP samples (0.26 mg/L). Conclusions: Macronutrient content is relatively unaffected by processing; Holder pasteurization and retort processing maintain similar fat, lactose, and total protein levels. Lysine and thiamine were significantly decreased by retort processing, but not by Holder pasteurization. Thiamine losses are clinically significant, and fortification may be necessary if SS donor milk is a long-term feeding choice.}, number={5}, journal={JOURNAL OF PEDIATRIC GASTROENTEROLOGY AND NUTRITION}, author={Lima, Hope and Vogel, Kenneth and Wagner-Gillespie, Montana and Wimer, Courtney and Dean, Lisa and Fogleman, April}, year={2018}, month={Nov}, pages={649–653} }

There is extensive research that provides an overview of the impact of Holder pasteurization on bioactive components of human milk. A shelf-stable (SS) human milk product, created using retort processing, recently became available; however, to our knowledge, little has been published about the effect of retort processing on human milk. Objective: We aimed to assess the ability of retort processing to eliminate bacteria and to quantify the difference in lysozyme and secretory immunoglobulin A (sIgA) activity between Holder pasteurized (HP) and SS human milk. Methods: Milk samples from 60 mothers were pooled. From this pool, 36 samples were taken: 12 samples were kept raw, 12 samples were HP, and 12 samples were retort processed to create an SS product. All samples were analyzed for total aerobic bacteria, coliform bacteria, Bacillus cereus, sIgA activity, and lysozyme activity. Raw samples served as the control. Results: One raw sample and 3 HP samples contained B. cereus at the time of culture. There were no detectable bacteria in SS samples at the time of culture. Raw samples had significantly greater lysozyme and sIgA activity than HP and SS samples (P < 0.0001). HP samples retained significantly more lysozyme and sIgA activity (54% and 87%, respectively) than SS samples (0% and 11%, respectively). Conclusions: Human milk processed using Holder pasteurization should continue to be screened for the presence of B. cereus. Clinicians should be aware of the differences in the retention of lysozyme and sIgA activity in HP and SS products when making feeding decisions for medically fragile or immunocompromised infants to ensure that patients are receiving the maximum immune protection.}, number={8}, journal={CURRENT DEVELOPMENTS IN NUTRITION}, author={Lima, Hope K. and Wagner-Gillespie, Montana and Perrin, Maryanne T. and Fogleman, April D.}, year={2017}, month={Aug} }

Objective The objective of this study was to model chronic human maternal malnutrition and measure effects of methylating-vitamins (MVs, containing choline, folate, B-6, B-12, and riboflavin) and docosahexaenoic acid (DHA) supplementation on fetal growth and development. Methods Pregnant gilts (n = 24) were either fully nourished (2.0 kg/d) with a corn-plus-isolated-soy-protein basal diet (control) supplemented with MVs and DHA or nourishment was restricted throughout gestation. Basal diet fed to malnourished gilts was reduced progressively from 50% to 70% restriction (1.0 to 0.6 kg/d) and was supplemented following a 2 (±MVs) x 2 (±DHA) factorial design. Full-term c-sections were performed to assess impacts on low and normal birth weight (LBW/NBW) fetuses (n = 238). Results Body weight gain of malnourished gilts was 10% of full-fed control dams (P < 0.05), but offspring birth weight, length, girth, and percentage of LBW fetuses were not different between treatments. The number of pigs per litter was reduced by 30% in malnourished control dams. Fetal brain weights were reduced by 7% compared to positive controls (P < 0.05). Micronutrient supplementation to malnourished dams increased fetal brain weights back to full-fed control levels. Dams with DHA produced offspring with higher DHA concentrations in brain and liver (P < 0.05). Plasma choline concentration was 4-fold higher in fetuses from unsupplemented malnourished dams (P < 0.0001). Global DNA methylation status of fetuses from restricted dams was higher than in control fetuses, including brain, liver, heart, muscle, and placenta tissues (P < 0.05). Addition of DHA increased methylation in LBW fetal brains (P < 0.05). Conclusions Despite the mobilization of maternal stores, malnourished litters displayed reduced brain development that was fully mitigated by micronutrient supplementation. Severe maternal malnutrition increased global DNA methylation in several fetal tissues that was unaltered by choline and B-vitamin supplementation.}, number={3}, journal={Current Developments in Nutrition}, publisher={Oxford University Press (OUP)}, author={Lima, Hope K and Lin, Xi and Jacobi, Sheila K and Man, Caolai and Sommer, Jeffrey and Flowers, William and Blikslager, Anthony and Gonzalez, Liara and Odle, Jack}, year={2017}, month={Dec} }
